FLANGING- SECEFICATION forming'part of Letters Patent No. 350,412, dated October 5, 1886.

Serial No. 203,934. (No model.)

To all whom it may concern:

` Be it known that I, ROBERT A. CARTER, residing at Pittsburg, in the county of Alle` gheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Flanging-Machines, of which improvements the following is a specification.

Fig. 11 is a, view in side elevation of the Hanging-table and front housing, the table being provided with a tail-stock and tool-rest and mechanism for operating the latter, the upper roll being provided with a suitable chuck. Fig. 12`is a top plan view of the same. Fig.18 is a sectional view on the line z z of Fig. 12. Fig. 14 is a perspective view of a chuck for use with the upper roll.

rlhe invention herein relates to certain improvements in machines employed in the manufacture of boilers and other like articles, and has for its object such a construction and combination of parts as will adapt the machine now employed for the Hanging operation only to a large numberv of the operations necessary in the construction of boilers, which operations are now'performed on separate and independent tools.

The constructions, combinations, and additions hereinafter described adapt the machine,

for use in Hanging regularly and irregularly shaped plates, nozzling, cutting, and threading pipes, bolts, or nuts, and also to such operations as require the use of lathes.

In general terms, the invention consists in the construction and combination of parts, substantiall y as hereinafter described and claimed.

The general construction and arrangement of the machine herein is similar to that shown and described in Letters Patent No. 328,274,

dated October 13, 1885, the standards 1,for supporting the upper roll, 2, being formed or cast on the bed-plate 3, as shown and described in said patent, said bed-plate being mounted on a suitable foundation. The upper roll, 2, is made hollow throughout its entire length, as indicated by dotted lines in Fig. 1, fora purpose to be hereinafter stated, and on its rear end are mounted the driving-pulley 4 and the broad-faced pinion 5, adaptedto interniesh with the gear-wheel 6 on the shaft 7 of the lower roll, 8. rlhe forward end of the roll 2 is mounted in an eccentric adjustingsleeve, as fully described and claimed in the patent above referred to, said sleeve being operated by a worm and gear, 9, as therein set forth. The rear bearing for the roll 2 is formed by a sleeve, 10, surrounding theroll and provided with exterior screw-threads for engagement with a threaded opening in the rear standard l. (See Fig. 1.) On thefront end of thesleeve 10 is formed or secured a hand operatingwheelyll, to which is bolted a ring, 12, provided with an inwardly-projecting Hange, 'which engages a collar, 13, on the roll 2, thus locking the sleeve to the roll as regards longitudinal movement, any longitudinal adjustment of the roll being effected by rotating the sleeve in the standard 1. The shaft 7 of the lower roll, 8, is mounted at its rear end in suitable bearings in the rear standard, 1, and at its forward ond in a post, 14, secured' in any suitable manner to the machine. The swinging table 15 is pivoted or hinged to the front housings, in the manner described and shown in the patent above mentioned, and reference should be had thereto for such construction. One exception to the construction as set forth in said patent should be noticed, and that is in regard to the pintle-pin 15, the upper surface of which is shown par- SSI tially cut away in the patent, whereas it is now shown with its upper surface flush with the surface of the table, for the purpose of permitting of the ilanging of rectangular plates, or such as have one or more straight edges. In the upper side of the table are mounted a series of frictioiri'olls, 16, having their axes parallel with the axis of the roll 2, and adapted to support the plate during the ilanging operation.

In the table l5 are formed three or more longitudinal slots, 17, one of which is in line with the upper roll, 2, as shown. Along the edges of these slots are formed ways 1S, for the re ception of lateral wings projecting from sliding blocks i9, 20, and 2l, located in said slots, the blocks being shown in dotted lines in Fie. 2. These block are held in position by nut-s screwing onto a threaded boss on the lower ends of the blocks, said nuts bearing against the lower edges of the walls of the slots, as fully and specifically shown and described in the patent hereinbefore referred to.

Through the blocks 19, 20, and 21 are formed openings for the reception ofthe shafts 22, on which are mounted the guide-rolls 23, said shafts being held in position by the nuts 24, fitting on the threaded lower ends of said shafts. YThe rolls 23 areforme'd with peripheral grooves, the lower walls of said grooves being extended beyond the peripheries of the upper walls, as shown in Figs. l, 2, and 5. The shafts 22 are extended above the rolls 23, and ou them are secured the arms 27, and on the inner ends of these arms are mounted the pressurerolls 2S, and through the outer ends ofsaid arms pass the adj listing-screws 29, bearing at their lower ends upon the table l5. In one side of the block 20 is formed a recess having one of its walls grooved and threaded, forming one halt' of a nut7 the other half of said nut being formed. by a removable block, 30, as shown in Figs. S and 9. The blocks l?) and 21 are similarly constructed. Through the nuts thus formed in the several blocks are passed the threaded rods 3l, 32, and 33, (see Fig. 2,) said rods being supported and held at both ends as against longitudinal movement by straps or other suitable devices secured to the under side of the tabe. The ends of the rods project beyond the frontend of the table, and are squared for the. reception of a wrench or an);r suitable operating-tool.

To the arms 34. of the table 15 are bolted the toothed segments 35, with which the pinions 3G on the shalt 37 intermesh, said shaft being suitably journaled in standards 38, bolted to the bedplate of the machine, and also being provided with hand-wheels 39, by which the shaft and pinions are rotated for raising and lowering the table.

In the inner faces of thesegments 35 are formed circular grooves 4:0,which engage lugs 4l, projecting from the bed-plate 3 or other part of the machine, when the table is turned to or is turned approximately to a vertical po-A sition, and prevent any lifting of the table from its bearings during the flanging operation. The pulley 4 is driven' by any suitable reversible mechanism.

The machine organized and arranged as above described is intended for flanging reetangular plates, or such as have one or more straight edges. l'n flangin g rectangular plates the rolls 23 are adjusted to such relation with the edging-rolls 42, mounted in the face of the front housings, that the distance from the edgingrolls 4.2 to the bottom of the grooves in the rolls 23 is equal to the width of the plate to be lianged. The plate is then fed in edgewise between the rolls 2 and 8, and into the grooves iu the rolls 23. The rolls 2 and S beingstarted, the plate is drawn along between them, the table being gradually raised. As soon as the end of the plate is drawn into the rolls 2 and S, or approximately so, they are reversed, thus moving the plate in the opposite direction. This back-and-forth movement of the plate is continued until the table is turned to a vertical position, or approximately so, and the fiange on one edge formed. The plateis then withdrawn and reversed, the iianged edge being placed between the side of the rolls 28 and one wall ofthe groove in the rolls 23, the portion of the plate adjacent tothe flange resting and being held upon wall or flange 25 of the rolls 23, as clearly shown in Fig. 5, by the rolls 28, the adj listing-screws 29 being op erated to cause the rolls 2S to bear ii rmly upon the plate `inside of the flange.

To adjust the rolls 28 to the varying thicknesses ot' plates to be operated the arms 27 are slotted, thereby permitting the rolls 2S to be moved to or from th'e rolls 23, as required. After the partially-flanged plate has been secured between the rolls 23 and 2S,as above stated,the blocks 1.9, 20, and 2l are moved by the screws 31., 32, and 33 toward` the Hanging-rolls until the edge to be flanged rests against the edgingrolls Lt2. The Hanging is then effected in the manner above stated. In case the machine is to be used for Hanging circular plates, the rolls 23 and theirconneetions are removed,and the circular plate can be secured to the block 20 in the manner described in the patent hereinbe'fore mentioned.

Thenext step in the operation is the formation of flue or man holes. This operation is effected by clam ping the plate against the bedplate 43, which is secured in any suitable manner in front of the machine, preferably immediately under the frontend of the table 15, so as to serve as a support :for the table when in a horizontal position, as shown. The bedplate is provided with an opening sur rounded by an annular boss, 44, proj ceti ng inwardly, and with adj ustablc guides 45, arranged on each side and below the boss, as shown, for centering and supporting the plate to be operated on. The guides having been properly adjusted, the plate is placed in position and a hole cut therein by the device shown in Fig. 4, which will be hereinafter described. The cutting device being romoved,thetine-forming IOC IIO

IIS

tool is substituted therefor. The flue-forming tool `consists of a head, 46, provided with a series of friction-rollers, 47, arranged around its periphery. rIhis headis secured to a threaded shaft, 48, on which is arranged a nut, 49, provided with handles 50. To this nut is attached the annular clamp 51, by means of clips 52, bolted to the clamp and engaging a flange formed on the nut. In forming the flue-hole the shaft 48 is passed through the hole in the platefromthe front,asshownin Fig. 1. Thenthe nut and clamp are placed over the shaft and the former turned up until the head 46 is drawn partially into the hole in the plate, andthe clamp presses the plate firmly against the boss 44. Then the squared end ot' the threaded shaft 48 is connected by a sliding sleeve, 53, to a squared section of shafting, 54, connected by a suitable coupling to the frontend of vthe shaft 7 of the lower roll, 8, of the Hanging-machine. By starting the machine. the shaft 48 and head 46 are rotated, and, an operator holding the n ut stationary, the head is drawn through the plate, forming a flanged fluehole. As the shaft and head move along, the sleeve slides along the shaft-section 54.

In cutting holes in the plate a cutter-bar, 55, provided with radially-adjustable cutters 56, (see Fig. 4,) is substituted for the Hanging-head 46. In using the cutter the plate is placed against the boss 44 of the bed-plate 43. The small end of the shaft 48 is then inserted througha small centering-hole in the plate,

as shown. The shaft 48 is then rotated by the shaft 7, with which it is connected by the sleeve 53, said sleeve fitting over the squared section 54 and the similarly-shaped end of the shaft 48,and bearing at its ends against a shoulder on the shaft 7 and against the nut 49. As the shaft 48 is rotated, the nut 49 is held stationary, thereby 'causing a forward feed of said shaft 48, the nut being held as againstany rearward movement by the sleeve 53. The squared end of the shaft 48 should be sufficiently long to permit of the necessary longitudinal movement of said shaft without disengagement of the sleeve and squared end. As the motion of feed of the cutters is toward the bed-plate 43, the clamp 51 is omitted, the plate being held in position by the cutters.

To adaptthe machine for cutting and threading pipes, a block, 57, (see Figs. 6 to 9,) provided with a threaded spindle, 58, is placed on the block 20, in the middle slot of the table, the block 57 being held in place by a nut, 59, screwing on the projecting end of the spindle 58. `In each side of the block 57 are formed dovetailed grooves for the reception of correspondingly-shaped projections on slides 60 and 61. Two of these slides are .arranged on each side of the block 57, the slides 60 on one side having their adjacent ends suitably shaped to clamp a threading-die, 62. (See Figs. 8 and 10.) One of the slides 61 on the opposite side of the block has a suitable cutting-blade, 63, secured therein, friction-rolls 64 being mounted in the end of the other slide.

(See Figs.7, y

9, and 10.) An opening, 65, is formed through the block 57 for the passage of the pipe being cut or threaded.

In cutting or threading pipes a suitable chuck or clamp, 66, is secured in the end of the hollow upper roll, 2. Any form of chuck may he used, but I prefer to use one similar to that shown in Fig. 14, commonly known as a universal77 chuck, which can he attached tov the roll 2 in any suitable manner.

If desired, a lathe tail-stock, 67, may be substituted for the block 57, said tail-stock beingI secured to the sliding block 20 inhthe same manner as the block 57, as shown in Fig. 13, and a tool rest or support, 68, can be attached to the block'19. (See Figs. 11 and 12.) If, now, a'y suitable chuck, (S9-c. g., the one shown in Figs. 11 and 12, or the one shown in Fig. 14-be attached to the roll 2, a complete turning-lathe adapted for all ordinary uses is formed.

In order to make the feed of the lathe automatic and also adapted for use in cutting screw-threads, a pinion, 70, is placed on the screw-rod 31, engaging the block 19, on which the tool-rest is mounted, and the pinion is arranged t-o engage apinion, 7l, on the countershaft 72, supported in hangers 73, bolted to the under side of the table 15. (See Fig. 11.) On the inner end of this counter-shaft is fastened another pinion, 74, engaging a gear-wheel secured to the shaft 7 of the under Hangingroll. By iuterposing idlers between the pinions and 71, as is the usual practice in screw cutting lathes, any-desired amount or direction of feed of the tool-rest can be produced.

While the table 15 is in use.for the purposes hereiubefore mentioned other than tlanging, I prefer to bolt it to the bed-plate 43, as shown in 1; or it may be held down by properly locking the hand-wheel 39.

I claim herein as my invention- 1. In a Hanging-machine, a `swinging table, slotted as described, in combination with one or more movable blocks located in said slots and one or more guide-rolls mounted on said blocks, substantially as set forth.m

2. In aflangiug-machine, a swinging table,
